Supergirl bosses confirmed as much Wednesday, noting that Season 3 will adapt the character’s “Worldkiller“” storyline from the comics (tweaked so Annable won’t be white-skinned and leather-clad at all times). The character was alluded to in Season 2’s closing moments, as Kryptonian flashbacks revealed a third, blood-dripped baby rocketed to Earth to “reign” over it.

Says executive producer Andrew Kreisberg of the new threat:

Greg [Berlanti] and I have wanted to work with Odette for years. We are beyond excited to have her join our cast in the scary, powerful and heartbreaking role of Reign.
